Description

[Technical field]

[0001] The present invention relates to a dynamic vibration absorber for transport cargo, and more particularly to a dynamic vibration absorber for transport cargo that can control and reduce the impact and vibration that cargo receives during transportation, thereby maintaining product quality. [Background technology]

[0002] Damage to products and parts occurs due to fatigue damage caused by minute vibrations and large impacts. Packaging designs are made to deliver products to users, but accidents that seem to occur during actual transportation and handling are occurring frequently, which is a burden on the industry. Therefore, in order to reduce vibrations during transportation, the inventor has devised a cargo material in the "Dynamic Vibration Absorber for Transported Cargo and a Transportation Method Using the Same".

[0003] In the practical application of this vibration control material, there was a demand for it to be more resistant to shocks, and to be lightweight and low-cost. Through experiments and structural review, we came up with this idea. [Prior art documents] [Patent documents]

[0005] Cargo materials that could withstand the vibrations and shocks that occur during transport were needed. The object of the present invention is to provide a dynamic vibration absorber for transporting cargo that can reduce or prevent damage to packaged items caused by vibrations and shocks that the cargo receives during transport, and can maintain the quality of the packaged items in good condition, and a transportation method using the same. [Means for solving the problem]

[0006] We have found a structure that provides shock absorption through the gas or soft structure of the liquid tuned damper, thereby reducing both vibration and shock. The present invention is composed of an intermediate layer structure with a cushioning function and an internal structure with a vibration-damping function. The intermediate structure is given a cushioning function by using a small mass of gas or space to respond to "shocks."

[0007] In the present invention, the impact is mitigated by the time it takes for the gas to deform, as the impact peak becomes lower. In the later stages, the fluid is deformed with a delay to absorb the energy. The energy is converted into thermal energy, but the amount of energy is low and it is easy to dissipate the heat. Effect of the Invention

[0008] The present invention can provide a dynamic vibration absorber for transported cargo that has the ability to reduce or prevent damage to packaged items caused by vibrations that the cargo is subjected to during transport, and maintain the quality of the packaged items in good condition, and a transportation method using the same. In particular, it will reduce constant vibrations, as well as shocks that are difficult to predict and design, at low cost, thereby reducing transportation losses in Japanese industries.

Claims

[Claim 1] Vibration-damping equipment for transporting cargo with shock-absorbing and vibration-damping functions and a transportation method using the same Vibration control equipment for transporting cargo consists of an internal vibration control structure, an intermediate layer with a cushioning function, and an exterior material to house it. The internal vibration-damping structure is made of a fine cellular tissue or a collection of small containers that contain fluids and gases. The middle layer with a cushioning function is a soft tissue or a cellular tissue filled with gas that has a cushioning function that supports and contains the internal vibration-damping structure. The exterior material retains and contains the function of the structural material, has a rigidity resistance that can withstand repeated use, and has a frictional holding force that transmits the vibration-damping function to the upper level of the cargo.
